The underlying theme of TrekLens is learning more about the world through photography. TrekLens fosters this by allowing photographers to display their work grouped by regions in a supportive and orderly environment. This is accomplished by an easy-to-use system which encourages people to critique each other's work. Integrated with this system are forums designed to encourage discussion about specific photos, countries, and general topics. Since TrekLens is globally oriented, it is completely multilingual capable, allowing for the widest audience possible. Ultimately, TrekLens depends on the civility, honesty and participation of its members.
MOST AVID PHOTOGRAPHERS devote considerable time and energy to studying their craft and refining their skills, with the goal of improving the “quality” of their images. Certainly, our primary mission at Photographic is to provide sound instructional material that enables our readers to become more proficient photographers. In defining “quality,” however, it’s all too easy to get hung up on technique and ignore the emotional impact—either positive or negative—of the images we create.
